Title: Improvements in or relating to devices for the accurate recording of time intervals
IPC: G07C1/08
Filed: 1921-04-26
Abstract: 182,966. Wood, A. S., and Ford, J. M. April 26, 1921. Recording particular operations.-Relates to recording-mechanism of the chronograph type and comprises means for enabling time intervals to be accurately recorded and measured from the record. The record sheet is driven by a phonic motor B controlled by a tuning-fork C and may be a disc, or, as shown, a sheet mounted on a drum A. The record may be made on a strip driven by the drum A which is either roughened, or provided with pins to engage perforated edges in the strip. The pen or style is mounted on a resilent lever arm P secured to a standard O and carrying an armature for an electromagnet M. The magnet may be doubly wound with coils of opposite polarity, the circuits of which are made and broken by the mechanism to be timed. Alternatively, singly-wound magnets may be employed, the time between the make and break of the circuit being taken; or separate electromagnets on opposite sides of the lever arm P may be employed. In the last case, one of the magnets is preferably permanently energized, the other, which is only energized during the time interval to be measured, being the stronger magnet. The pillar 0 and magnet are mounted on a base L supported on their screws L' of which one is provided with an adjusting milled' head L<2>. A bracket Q adjustable in length engages the lever P. The base L is held to a table H by a screw L' with a spring washer. The table H is held to the frame of the instrument by four screws J working in slots in the table and fitted with spring washers, the frame having ribs G or four studs to carry the table, the lateral movement of which can be effected by a nut thereon engaging a screw K<1> with milled head. The cores of the magnets are laminated and large resistances placed in circuit with the windings to lessen hysteresis effects. Several markers as shown may record on the same drum, and the drum or markers may be traversed so as to employ more than one revolution for the record. The traversing may be effected through relays only with a record being taken. In order to avoid error due to eccentricity of the drum in reading the record a pointer E mounted on the spindle of the record drum may be read against a fixed dial, the marks being brought against the recording point and the dial read. Sag error is minimised by adjusting the length of the bracket Q.

Patent GB-1317837-A (GB)
Title: Method for forming a honeycomb structure and resulting articles
IPC: C03B23/207
Filed: 1971-04-30
Abstract: 1317837 Forming a honeycomb structure from glass tubes BENDIX CORP 30 April 1971 [7 May 1970] 12490/71 Heading C1M A honeycomb structure is formed by arranging a plurality of glass tubes in side-by-side relationship to form a stack having interstitial spaces between the tubes and heating the stack to a temperature sufficient to soften the glass, without applying any external pressure, but maintaining the interstitial spaces at a pressure that is at or below atmospheric, thereby at least partially closing the interstitial spaces. Each tube preferably has a ratio of wall thickness to outer diameter between 0À01 and 0À25. The tubes may consist of an outer layer 18 and a central support layer 20, (Fig. 2), two layers having similar thermal coefficients of expansion and the layer 20 has an annealing point between 50‹ and 200‹ C. higher than the outer layer 18. The tubes may further have an inner layer having a coefficient of expansion similar to the other layers. Preferably the axis of outer layer thickness to outer diameter is between 0À005 and 0À15. To produce a structure in which the tubes have rectangular cross-sections the tubes are stacked with their axes parallel and so that the line of contact of each interior tube with its neighbours are spaced at 90 degree intervals (Fig. 5). To produce a hexagonal crosssection structure the tubes are arranged so that the lines of contact are at 60 degree intervals (Fig. 6). To produce a structure from tubes having only a single layer the interstitial spaces are evacuated. This is carried out by initially immersing the crop of the stack in a sealing liquid so that the liquid rises into the tube interiors and interstitial spaces by capillary action, the liquid rising higher in the tubes. The stack is then cut above the point which the liquid has reached in the spaces but below the point it has reached in the tubes, thereby producing a stack in which the tubes only are sealed. Then the stack is heated while one end is connected to a vacuum pump.
Patent GB-125119-A (GB)
IPC: C22B23/00
Abstract: 125,119. Annable, H. W. C., and Nickel Concentration, Ltd. May 27, 1916. Nickel carbonates, oxides, sulphates, and sulphides.-Silicate ores of nickel, such as garnierite, are roasted so as to obtain a mass containing sulphate of nickel. The mass is discharged into water for dissolving out the sulphate of nickel; in some cases a basic sulphate of nickle is formed during the roast, and, in such cases, the basic sulphate may be dissolved by adding hydrochloric acid to the water; this acid may be obtained from the gases from the furnace in which the ore is roasted. The nickel may be recovered from the solution in several ways. It may be precipitated as carbonate, by adding magnesite, or as sulphide, by adding sodium sulphide, or the furnace gases may be passed into the solution either directly or after removal of hydrochloric acid. If the acid is thus removed, the nickel solution should be neutralized, e.g. by the addition of a little chalk before passing in the furnace gases, and a quantity of chalk more than sufficient to neutralize the acid is added to the solution, when the furnace gases are used directly. The precipitated salt of nickel is dried and heated in the air to obtain nickel oxide, which is found to contain approximately 90 per cent. of nickel oxide, and similarly, when the nickel is precipitated as carbonate, this is separated, dried, and ignited to obtain nickel oxide. Some of the magnesium in the ore is converted, during the process, into magnesium sulphate.

Title: Improvements in dividing apparatus chiefly designed for use with gear-cutting machines
IPC: B23F23/08
Filed: 1925-05-18
Abstract: 242,892. Wujanz, G. May 18, 1925. Indexing.-In a dividing-mechanism, particularly applicable to gear generating machines of the reciprocating cutter type having indexing- mechanism incorporated in the gear trains for producing the rolling movements, a wheel a driven from the toolhead, imparts synchronous rolling movement to the blank through clutch members b, i and a wheel q connected to the blank spindle and the drive between the clutch members b, i is interrupted during the backward rolling movement for a period corresponding to a blank rotation through one or more pitches. The clutch member b is provided with a pin d carrying a three armed driver e which during the forward rolling movement engages an abutment o on a cam piece k secured in the clutch member i. At the beginning of the backward rolling movement the driver e moves away from the surface o and the member i remains stationary until the driver e is moved axially by an inclined surface on the cam k into the path of a second abutment in the clutch member i, which thereupon takes part in the rest of the backward movement. The driver is retained in position during this movement against a spring h by a pin m coacting with the driver-arm t. When the next forward movement commences the driver is disengaged from the pin m by a spring f and is thereupon moved axially by its spring h until the arm again engage the abutment o for a fresh cycle of operations. The lost motion of the member i between successive forward movements is thus equal to one revolution of the clutch member i corresponding to the required indexing- movement of the blank.
